Effective Codes

Adopted by City Council last March, the new City of Fort Collins building code green amendments went into effective January 1, 2012. For the complete codes, visit code and standards.


The newly implemented Green Code Amendments requires a combustion safety test be performed on natural gas appliances with draft hoods. The code requirement is applicable to all single-family and multifamily projects. As part of this new requirement, the combustion safety test must be performed by an approved agent of the City of Fort Collins.
